Vertical / horizontal stacks and tiny tiny gauges

I want a row of gauges across the top of my UI (8 or so)
then I want three gauges on the next row down to the left
then I want two graphs under these.

Basically this, but with the top row readable and the second / third rows justified to the left.

I thought taking my 8 gauge row out of the vertical stack would make them fill the page but they do not, what am I doing wrong?

Just to advise, even taking all the cards out apart from the top 8 doesnt make them fill the screen, its almost like its forcing it to keep that width for some reason?

Is this something to do with the fact i have the IOS app too? as the 8 gauges fill my iphone screen left to right?
